The invention discloses a photobioreactor which aims at providing a set of solution scheme for cultivating microalgae with simple production, convenient disassembly and high efficiency. The photobioreactor comprises a buffer / gathering system, a detecting device, a reaction region and a gas exchange device, wherein the buffer / gathering system is a transparent drum with a taper-shaped bottom and isconnected with two pipelines respectively used for cycle cultivation and microalgae collection; the detecting device is introduced from the upper part of the buffer / gathering system; the reaction region comprises a plurality of circular transparent photoreaction tubes; and the gas exchange device is connected with the inner part of the reaction region. The photobioreactor realizes the circulationof a cultivation system through a peristaltic pump, adjusts the ventilation of each photoreaction tube through a gas pump and a plurality of gas valves, has simple and convenient operation and high mass transfer efficiency, and is suitable for fast cultivation of microalgae with a large number.

The invention discloses a speed reducer improving the protection performance. The speed reducer comprises a shell. The two sides of the outer portion of a transmission shaft are connected with a first gear and a second gear correspondingly. The outer side of the transmission shaft is sleeved with a stable base. Clamping blocks are arranged on the top and the bottom of the stable base. The top of the first gear is engaged with a first transmission gear. A first rotation shaft penetrates the middle portion of the first transmission gear in a connected manner. The bottom of the second gear is engaged with a second transmission gear, and a second rotation shaft penetrates the middle portion of the second transmission gear in a connected manner. The outer side of the shell is sleeved with a protection shell. Ventilation holes are formed in the top and the bottom of the inner side of the shell. An electric motor is connected to the inner side of the installing base. The outer side of the rotation rod is connected with cooling blades. A conical base is arranged on the right side of a machine cover. The speed reducer has the beneficial effect that the protection performance of the speed reducer is improved, and the problem that due to reduction of the protection performance, the service life of the speed reducer can be shortened is solved.

The invention discloses a ball collection device for basketball training, and aims at changing the current situation that basketballs are put in a box or a sleeve net. A plurality of bearing bracketsare arranged in a box body, a plurality of side-by-side embedment frames are embedded into each bearing bracket separately, the embedment frames are equidistantly hinged with a plurality of hinged supporting plates adjacent to one another vertically in sequence from top to bottom, the hinged supporting plates are of a curved-plate-shaped structure sunken downward from the center of the upper end face, basketballs are placed on the hinged supporting plates one by one, because the basketballs are separately placed on the hinged supporting plates, the contact area between the basketballs and thehinged supporting plates is larger, the deformation of the basketballs under pressure can be effectively avoided, and the storage under the situation that the basketballs are not used for a long timeis facilitated; the bottom of the box body is provided with universal wheel capable of locking, and the front end and rear end of the box body are fixedly provided with push-pull frames respectively,which provides convenience for pushing and pulling the box body to move, thereby being capable of reducing the workload of carrying the basketballs; a gap exists between every two adjacent bearing brackets, so that the stored basket situation is observed, and it is checked whether or not missing of the basketballs or the flat and thin shape of air leakage occurs.
